Enterprise Architecture

Enterprise Architecture establishes the statewide roadmap to achieve the state’s
mission and goals through improving the performance of its core business
processes within an efficient information technology (IT) environment. Simply
stated, Enterprise Architecture is a “blueprint” for systematically and completely
defining the state’s current (baseline) or desired (target) technology environment.
Enterprise Architecture is essential for evolving information systems and
developing new systems to optimize mission value. If defined, maintained, and
implemented effectively, Enterprise Architecture assists in optimizing the
interdependencies and interrelationships among the state’s business operations
and the underlying IT that support operations.

Established in 2005, the California Enterprise Architecture Program (“CEAP”) is
charged with developing a comprehensive Enterprise Architecture for the
Executive Branch’s IT program. Since its inception, CEAP has released a series
of Enterprise Architecture publications.2 The first and most important document
is the California Enterprise Architecture Framework (July 15, 2005), which
defines an end-to-end process to initiate, implement, and sustain an enterprise
architecture program (see Appendix E). It is the roadmap for the Executive
Branch’s enterprise architecture efforts. CEAP has also published a series of
papers on “Service Oriented Architecture” that provide the key information
needed to design and build shared services in a federated web environment.
Technical Reference Model (TRM) documents were produced classifying
technology into seven domains along with guidelines, templates, and process
details to ensure technology is defined in a consistent way across the state
enterprise. In 2007, the state began work on a Business Reference Model that
will serve as the foundation for defining state government business functions and
the delivery of services. The Business Reference Model is a high-level
representation of the vision, mission, goals and objectives that comprise the
strategic business of government
